M2 stylus with 1.0 mm diameter carbide cylinder and 3.0 mm diameter x 7.0 mm long stainless steel base. Overall stylus length is 36.0 mm. Stylus weight is 0.63 gram. Compare to Renishaw A-5003-1218. Cylinder styli are used for edge probing on stampings or sheet metal parts. They are not suitable for high accuracy work because the form of a cylinder is not as precise as a sphere.
